About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559683657. Listed at 7 retailers as of October 30, 2026, with prices from €2,483 to €4,910, a €2,427 spread on the same certified stone. NZ Jewellers lists it at €4,910. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
